Question

Define three defects of vision and their corrections

Answer 1

Myopia - If a person is able to see near objects clearly but see farther objects blurry, he is known to be suffering from myopia.
Hypermetropia - If a person have difficulties seeing closer objects, he is known to have hypermetropia.
Presbyopia - As we get older, our lens on eyes gets old and we gave difficulties to see near objects clearly.

Myopia can be corrected by using concave lenses while Hypermetropia and Presbyopia can be corrected using convex lenses.
